What is the functional connection between the nucleolus?

and the ribosomes.

The nucleolus is a structure found within the nucleus of eukaryotic cells. Its primary function is to assemble ribosomal subunits, which are essential for protein synthesis. The nucleolus contains the genetic information necessary for producing ribosomal RNA (rRNA) and combines it with proteins to form the small and large subunits of ribosomes.

Once assembled in the nucleolus, the ribosomal subunits are then transported out of the nucleus to the cytoplasm where they combine to form functional ribosomes. These ribosomes are responsible for translating messenger RNA (mRNA) into proteins through a process called translation.

Overall, the nucleolus plays a crucial role in the production of ribosomes, which are key players in protein synthesis and essential for cellular function and survival. This functional connection between the nucleolus and the ribosomes highlights the importance of this organelle in the overall functioning of the cell.
